given the function rule f(x)=x^2-4x+3, what is the output of f(-3)

I do not remember exactly what to do, but I think you should try to substitute x with -3. This is because

f(-3) is the same as f(x), except that x is already provided.

(-3)^2 -4(-3) + 3

9 + 12 + 3

To find the output of the function f(x) = x^2 - 4x + 3 when x = -3, you simply need to substitute -3 into the function and calculate the result.

1. Start with the function f(x) = x^2 - 4x + 3.
2. Substitute -3 for x in the function: f(-3) = (-3)^2 - 4(-3) + 3.
3. Simplify the expression inside the parentheses: (-3)^2 = 9 and -4(-3) = 12.
4. Substitute the simplified values back into the equation: f(-3) = 9 - 12 + 3.
5. Perform the calculations: 9 - 12 = -3, and -3 + 3 = 0.

Therefore, the output of the function f(-3) is 0.
